BRAKE-BLOCK,

SPECIIE'ICATIGN forming part of Letters Patent No. 378,215, dated February 21, 1888.

. Serial No. 253,959. (No model.)

To aZZ whom it may concern-.-

Be it known that I, GEORGE ALLEN POSSON, of Angwin, in the county of Napa and State of California, have invented a new and Improved Brake-Block, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved brake block especially adapted for vehicles,and from which the brake shoe can be easily and quickly removed when worn out and a new one inserted.

The invention consists in the construction and arrangement of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of my improvement. Fig. 2 is a sectional side elevation of the same; and Fig. 8 is a perspective view ofa modification of my improvement.

My improved brake-block A is made of two principal parts-the brake-shoe B and the back the brake bar of the brake mechanism. The brake-shoe B maybe of rubber,wood, or other suitable material.

As shown in Figs. 1 and 2, I provide the back 0 on its upper part with two sidewise extending flanges, H, fitting over the sides of the brake-shoe B. A bolt, I, passes through said flanges and through the brake-shoe B transversely, thus holding the upper part of the brake-shoe in place in the back 0. The lower end of the latter is provided with a flange, J, passing under the bottom of the brake-shoe B, and provided on its inner end with an upwardly-pointed projection, J, driven into a groove in the bottom of the brake-shoe B, so that the lower part of the latter is also held securely in place on the back G. The latter is also provided with the rearward]y-eXtending bolts K, by which the bake-block is so cured to the brakebar.

For buggies and spring-wagons the metallic back will be made in two halves, as if out through from top to bottom, and each half is provided on its flange H with projections or hooks L,passing into apertures on the sides of the brake-shoe B, in place of the belt I, mentioned above, thus holding the shoe between the two parts, as in the jaws of a vise. Each half is also provided with ribs N, fitted onto the brake-bar, and provided with apertures through which passes a bolt for holding the halves on the brake-shoe and the brake-block on the brake-bar.

In the construction shown in Figs. 1 and 2 the brake-shoe B may be removed by simply withdrawing the bolt I and then lilting the brake-shoe B upward until it disengages the point of projections J. A new shoe is then fitted onto the back G, driven onto the projections J, and the bolt I is replaced, whereby said shoe is again securely fastened in place on the back 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combinatiomwith a brake-shoe, 13,0f a metallic back formed with upper side flanges, H, embracing the sides of the block, and with bottom flange, J, having upward-projecting points J entering the lower end of the shoe, substantially as set forth.

2. As a new article of manufacture, a back for brake-shoes comprising the metal plate 0, formed with upper side lugs, H, the bottom flange, J, having points J, and the attaching bolts K, projecting from the rear face of said plate, substantially as set forth.

3. The cornbinatiomwith a brake-shoe, of a back provided at its upper end with flanges fitting over the sides of said brake-shoe, a bolt passing through said flanges and through-said brake-shoe transversely, a flange formed on the lower end of said back and provided with upwardly-projecting lugs passinginto the bottom of the brake shoe, substantially as shown and described.

GEORGE A. POSSON.
